    1. Artificial Intelligence in Diabetic Eye Disease Screening

      Artificial Intelligence in Diabetic Eye Disease Screening

      Systematic or national screening programs for diabetic retinopathy (DR) and diabetic macular edema (DME), using digital fundus photography and optical coherence tomography (OCT), are currently implemented at primary care level, aiming to provide timely referral for vision-threatening DR and DME to ophthalmologists for timely treatment and vision loss prevention. However, interpretation of retinal images requires specialized knowledge and expertise in diabetic eye disease. Furthermore, current DR screening programs are capital- and labor-intensive, which makes it difficult to rapidly scale up and expand diabetic eye screening to meet the needs of this growing global epidemic. Deep learning (DL), a new branch ...

      Artificial intelligence and deep learning in ophthalmology

      Artificial intelligence (AI) based on deep learning (DL) has sparked tremendous global interest in recent years. DL has been widely adopted in image recognition, speech recognition and natural language processing, but is only beginning to impact on healthcare. In ophthalmology, DL has been applied to fundus photographs, optical coherence tomography and visual fields, achieving robust classification performance in the detection of diabetic retinopathy and retinopathy of prematurity, the glaucoma-like disc, macular oedema and age-related macular degeneration. DL in ocular imaging may be used in conjunction with telemedicine as a possible solution to screen, diagnose and monitor major eye diseases for ...

    3. Comparison Of Optical Coherence Tomography Angiographic Changes After Anti–Vascular Endothelial Growth Factor Therapy Alone Or In Combination With Photodynamic Therapy In Polypoidal Choroidal Vasculopathy

      Comparison Of Optical Coherence Tomography Angiographic Changes After Anti–Vascular Endothelial Growth Factor Therapy Alone Or In Combination With Photodynamic Therapy In Polypoidal Choroidal Vasculopathy

      Purpose: To compare changes in optical coherence tomography angiography in eyes with polypoidal choroidal vasculopathy after treatment with anti–vascular endothelial growth factor monotherapy or combined with photodynamic therapy . Methods: This is a longitudinal case-controlled study. The authors performed optical coherence tomography angiography at baseline and Month 3 in patients with treatment-naive polypoidal choroidal vasculopathy undergoing monotherapy (n = 10) or combination therapy (n = 13). We analyzed flow signal within the outer retina and choriocapillaris using automated segmentation. The authors analyzed the presence of pachyvessels using a 10.4- μ m segment through Haller layer . The changes in each layer were compared ...

    4. Retinal Imaging Techniques for Diabetic Retinopathy Screening

      Retinal Imaging Techniques for Diabetic Retinopathy Screening

      Due to the increasing prevalence of diabetes mellitus, demand for diabetic retinopathy (DR) screening platforms is steeply increasing. Early detection and treatment of DR are key public health interventions that can greatly reduce the likelihood of vision loss. Current DR screening programs typically employ retinal fundus photography, which relies on skilled readers for manual DR assessment. However, this is labor-intensive and suffers from inconsistency across sites. Hence, there has been a recent proliferation of automated retinal image analysis software that may potentially alleviate this burden cost-effectively. Furthermore, current screening programs based on 2-dimensional fundus photography do not effectively screen for ...
